1. A socket having a working end with a work piece aperture that is adapted to receive a work piece and an opposing drive end adapted to engage a torque application tool, the socket comprising:
a biasing member substantially disposed in the work piece aperture and adapted to apply a frictional force to the work piece when the work piece is received in the work piece aperture and including opposing first and second ends, wherein the first end is disposed proximal to the working end and is restricted from moving in a radial direction, and the second end is disposed distal to the working end and includes a bent portion and a terminal end; and
a groove formed in an internal surface of the work piece aperture, wherein the terminal end engages the groove and restricts the biasing member from moving in an axial direction, wherein the terminal end is adapted to move radially into the groove as the work piece is inserted into the work piece aperture, and move radially away from the groove when the work piece is retracted from the work piece aperture.
